tagptr

Strongly typed marked pointers for storing bit patterns (tags) alongside raw pointers for concurrent programming with atomic operations.

Build Status Latest version Documentation License

Usage

Add the following to your Cargo.toml

[dependencies]
tagptr = "0.2.0"

Motivation

Most atomic CPU instructions only work with register-sized memory words (e.g., 32-bit or 64-bit). Many low-level concurrent algorithms thus need to store aditional data (tags) in the unused lower bits of pointers to referenced data objects. This crate provides thin and efficient abstractions for working with such pointers.
